Use these matrices sparingly to expose who is responsible, who approves, who contributes, and who must be informed. Share the map where everyone can see it, and update after decisions. Beware performative complexity; empty boxes are signals too. Pair with ownership charters and service catalogs so newcomers navigate confidently and handoffs stop slipping through invisible cracks.
Invite input from people affected and those with expertise, then empower a decider to proceed once advice is gathered. Write who was consulted and how feedback changed the proposal. Encourage dissent in writing, not hallway whispers. This habit preserves autonomy without isolation, making decisions smarter and faster because perspectives are captured early while accountability remains crystal clear.
